Description

航空器黑匣子全球定位功能扩展装置 技术领域
本实用新型涉及一种航空器黑匣子辅助设备，特别涉及一种航空器黑匣子全球定位功能扩展装置。
背景技术
航空器通常装备一台飞行数据记录仪和一台机舱话音记录器，俗称黑匣子，一旦出现空难，整个事故过程中的飞行参数以及驾驶舱及机舱中的声音就能从这二个黑匣子中找到，人们便可知道飞机失事的原因。但是目前装备的飞机黑盒子没有全球定位的功能，仅仅提供了事故发生后黑盒子主动向周围发出37.5kHz脉冲信号，需要通过搜救定位仪完成搜索、跟踪、定位黑匣子。如果发生类似于MH370坠机前飞机所有对外通讯信号中断、且中断后又进行了长距离的飞行，就难于通过搜索黑匣子的脉冲信号找到它了。
尤其当航空器发生机上人员人为干预，例如驾驶人员或其它人员有意隐藏航空器去向；或非人为干预，例如：遭遇紧急状况，机上人员失去操控能力或缺氧昏迷，无法向外界发送航空器定位信息时，外界无法了解此航空器所处的位置。
